摘要

OBJECTIVE: The extratranial-intracranial bypass may have the potential lo improve hemodynamic cerebral ischemia caused by occlusive diseases of the main cerebral arteries. Inlraoperative confirmation of effective distribution of blood flow via the donor arteries to the involved region will assure? a successful bypass surgery. METHODS: Infrared thermography was used lo measure the temperature of the cortical surface at the operative field. Regional cerebral blood flow (rCBF) was measured with a laser Doppler flow meter. Changes in the cortical surface temperature before and alter temporary occlusion of the bypass were compared with changes in rCBP values in the corresponding sites. RESULTS: Thermographic examination demonstrated a heterogeneous increase of cortical surface temperature caused by the blood flow via the exlracranial-intracranial bypass and was closely related lo rCBF changes. CONCLUSION: Thermography is useful not only lo demonstrate the distribution of blood flow through ihe extracranial-inlracranial bypass but also to quantitatively evaluate the rCBF changes in the operative field.
